Kei Nishikori 

Injured Japanese star Kei Nishikori pulled out of the Australian Open yesterday, while Novak Djokovic says he will test his problem elbow before deciding whether to play. Nishikori has not played competitively since last August after suffering a torn tendon in his right wrist. He said he still wasn't ready for a gruelling Grand Slam campaign. "I am very sorry to announce that I will miss the Aussie Open this year," he said. "The Aussie Open is my favourite Slam... it's my 'home' Slam," he added. "It's the Slam that takes incredible care of the players and their teams, and it hurts that I will have to miss it this year."
